Objectives of energy Management
➢To achieve and maintain optimum energy procurement and utilization,
throughout the organization.
➢ To minimize energy costs / waste without affecting production & quality
➢ To minimize environmental effects.
➢ manage for Non-renewable resources to last longer.
➢Shifting towards RENEWABLE RESOURCES.(encl. news…)

Dependency of Energy Management on Auditing

7. Auditing Skill
PLAN:
“The verification, monitoring and analysis of use of energy
including submission of technical report containing recommendations for
improving energy efficiency with cost benefit analysis and an action plan
to reduce energy consumption".
The auditor begins by visually inspecting the exterior of the plant, looking
for clues of energy waste, ventilation, and outcome problems.

8. Need for Energy Audit
8
• The primary objective of Energy Audit is to determine ways
to reduce energy consumption per unit of product output
or to lower operating costs.
• provides a reference point for managing energy in the
organization.
• provides the basis for planning a more effective use of
energy throughout the organization.

9. Types of Energy Audit
❖The type of Energy Audit to be performed depends on:
Function and type of industry
❖Depth to which final audit is needed, and Potential and magnitude
of cost reduction desired Following are the two types Energy Audit-
i) Preliminary Audit
ii) Detailed Audit
9

10. 1. Preliminary Energy Audit Methodology
➢Estimate energy consumption in the organization
➢Estimate the scope for saving
➢Identify the most likely and the easiest areas for attention
➢Identify immediate (especially no-/low-cost)
➢improvements/ savings possibilities
➢Identify areas for more detailed study/measurement
➢Go for recommendations

11. 2.Detailed Energy Audit Methodology
➢Detailed energy auditing is carried out in three phases:
➢Phase I - Pre Audit Phase
➢Phase II - Audit Phase
➢Phase III - Post Audit Phase
**There are ten major steps for conducting Detailed Energy
Audit.(discussed further)**

16. Energy Audit Instruments
➢ Flue Gas Analyzer
➢ Stroboscope, Tachometer
➢ Ultrasonic Flow Meter, Manometer, Venturi-meter
➢ Voltmeter, ammeter, thermocouples
➢ Digital Thermometer (Non-contact and Contact type both)
➢ Anemometer, pH/TDS/Conductivity meter
➢ LUX Meter
➢Power Analyser

➢Boiler and steam system
➢Furnace
➢DG sets
➢HVAC and Refrigeration system
➢pumping system
➢Cooling tower
➢Compressed air system

18. Conclusion
The main expectation of this detail was to build on the previous energy
efficiency work that had been accomplished and further reduce
consumptions and costs, as such it can be seen as very successful: it
accomplished to discover measures which reduce the consumption.
